We use LiveChat (http://www.livechat.com/). They have a free version, but we pay up because we want the retention that some of their higher levels offer. Even still, I think it is only $50/month or so. We don't use it a ton, certain managers who have younger, tech savvy clients customers, seem to like it quite a lot.

No problem. Weird that they have the same name. The second one I found, though, seems a little more legit just because they actually do have a chat line on their website. The first one appears to be from Chicago, but as I said, I had problems contacting them.
